General Introduction Of Aspherical Lens
The Spherical Lens Is With A Constant Curvature From The Center Of The Lens To The Edge, While The Aspherical Lens Changes Continuously From The Center To The Edge. In Photographic Lenses, Many Aberrations Must Be Corrected In Order To Ensure Optical Performance. If Only The Spherical Lens Is Used To Correct, It Is Necessary To Have A Lot Of Lens Combinations For The Technical Requirements For Special Advanced Lenses, Spherical Lenses Are Sometimes Unable To Correct Aberrations To The Extent Of User Satisfaction. The Aspheric Lens Has A Better Radius Of Curvature And Can Maintain Good Aberration Correction To Obtain The Desired Performance. The Application Of Aspheric Lens Brings Excellent Sharpness And Higher Resolution, And The Miniaturization Design Of Lens Becomes Possible.
Performance Superiority Of aspheric Lenticular Lenses
a.Spherical Aberration Calibration
Aspheric Lenses Are Used To Replace Spherical Lenses, And The Most Obvious Advantage Is That The Spherical Aberration Of Spherical Lenses In Collimation And Focusing Systems Can Be Corrected. By Adjusting The Surface Constant And The Aspheric Coefficient, Aspheric Lens Can Eliminate Spherical Aberration To The Maximum Extent. Aspheric Lenses (rays Converge To The Same Point And Deliver Optical Quality) Basically Eliminate Spherical Aberration Generated By Spherical Lenses (rays Converge To Different Points, Leading To Blurred Image).
In Order To Increase The Effective Focal Length To Eliminate Spherical Aberration, Three Spherical Lenses Are Needed. However, With Only One Aspheric Lens (high Numerical Aperture, Short Focal Length) Can Achieve The Same Goal And It Can Also Simplify The System Design And Improve The Transmittance Of Light.
b. System Advantages
The Aspheric Lens Simplifies The Elements Involved To Improve The Optical Quality And Improves The Stability Of The System. It Can Achieve Similar Or Better Optical Quality, Thus Reducing The System Size, Increasing Cost Ratio And Reducing The Overall Cost Of The System.
